ADVERTISING DEVICE.

' Application filed January 14, 1922. Serial No. 529,303.

To all whom it may concern:

Be it known that I, GEoRon HAs'rlNos HARRrs, a citizen of the Dominion of New Zealand, residing at 20 1 Union Buildings, Custom Street east,Auckland,in the Provincial District of Auckland, a subject of the King of Great Britain and Ireland, have invented certain new and useful Improvements in Advertising Devices, of which the following is a specification.

This invention relates to devices for displaying advertisements and other information in or upon vehicles, ships and the like, and has for its object the provision of an improved device adapted to be operated by movement of the vehicle ship or the like.

According to the invention the device comprises a casing provided with a sight opening and containing rollers around which passes an endless band carrying the information it is desired to display through said opening.

A pendulum within the casing has its end above the point of fulcrum pivotally connected to a pawl which rides backwards and forwards on weighted ratchet wheel so as to impart intermittent rotary movement thereto. On the spindle of the ratchet wheel is keyed a disc having projecting from one side a roller, and a guide in the form of a segment of a circle.

The projecting roller during the course of the discs rotation enters radial slots open at the outer ends and formed in-a second disc keyed on a nearby spindle for the purpose of imparting rotary movement to said second disc.

Between the radial slots the periphery of the second disc is cut or formed with curves having the same radius as the segmental projection, whereby the latter is enabled to enter and fit the second disc and lock same against rotary movement during the time the roller on the first disc is not engaged in a radial slot in-the second disc.

A bevel wheel keyed on the same spindle as the second disc transmits the rotary movement imparted to the latter, to a bevel p nion driving a further spindle geared Wltll one of-the roller spindles in order that the rotary motion caused by the swinging of the pendulum will be duly transmitted to the roller for the purpose of causing same to move the endless band behind the sight openlng in the casing.

A check pawl is provided to engage the ratchet wheel and prevent movement of the latter in the reverse direction to that desired. v

The construction and operation of the device will. however be more particularly described with the aid of the accompanying drawing, wherein Figure 1 is an elevation of the device, showing the casing in section and Figure 2is a cross sectional view thereof with portion of the gearing omitted, while Figure 3 is a planview of the gearing omitting the pawls and the pendulum.

Referring to the drawing 1 is the casing formed with a sight opening 2 preferably glass covered, through which information or other matter placed on the band 3 may be viewed.

The band 3 passes around -a driven roller 4 and an idle roller 5 the latter being mounted in spring pressed bearings 6 in order that the band 3 will be kept taut.

In the casing 1 is the pendulum 7 pivoted at 8 in order that its upper end will be above the latter point.

A pawl 9 pivotally connected to the upper end of the pendulum 7 rides on a ratchet wheel -10 keyed on a spindle 11 and with which also engages a check pawl 12.

The ratchet wheel 10 is formed with or has attached thereto a weight 10".

A. disc 13 keyed on the spindle 11 has proj ecting from one side a roller 14 and a guide 15 in the form of a segment of a circle.

Near the spindle 1]. is another spindle 16 and on the latter is keyed a disc 17 containing equi-distant radial slots 18 open at their outer ends, said disc 17 having the portions of its periphery between said slots 18 cut away to provide curves 19 of the same radius as the segmental guide 15.

A bevel wheel keyed on the spindle 1.6

meshes with a bevel pinion 21 keyed on the same spindle 22 as a sprocket wheel 23 around which and a sprocket wheel 2 1 on the spindle of the roller 4 a driving chain passes.

r The pendulum 7 swings between spring buflers or steps 26, which limit its movement and also assist it to commence to swing in the opposite direction.

The device is placed so that movement of the vehicle ship or the like will cause the pendulum 7 to swing between the buffers or stops 26 and cause the pawl 9 to move back wards and forwards on the ratchet wheel 10. When moving forward the pawl 9 engages a tooth-of the wheel 10 whereby partial turning movement is imparted to the latter, the spindle 11 and disc 13.

The pawl 9 when moving backwards, rides over the teeth of the wheel 10. which is prevented trom turning in the reverse direction by the check pawl 12.

Intermittent turning movement is thereby imparted to the wheel 10 and during same the weight 10 is being raised to its highest position.

As the weight 10* comes to its highest position the roller 14 is presented to a radial slot 18.

The following turning partial movement of the wheel 10 by the pawl 9 causes the weight 10 to pass over the centre of the wheel 10whereby the latter makes approximately half a turn under the influence oi? the falling weight 10?, during which period the roller enters the slot 18 and imparts partial turning movement to the disc 17.

The projecting segmental guide 15 is formed and located so that as the roller 1 enters a slot 18, its end 15 will be slightly below'the centre of the wheel 10, thereby leaving the disc 17 free to turn.

Before however the roller 14- leaves the slot 18 at the finish of the partial turning movement of the disc 17 the end 15 of the segmental guide 15 will have entered the following curve 19 to again lock the disc 17 against-turning movement, said disc owing to the length of the guide 15 remaining to the spindle 22 and the wheels 2S, 24 being of equal diameter, a complete turn is there-i fore imparted to the roller causing the band 8 to be moved a distance equal to the circumference of said roller.

The sight opening 2 is made so that the desired area of the band 3 can be viewed between the movements of same. 7

What I do claim and desire to obtain by Letters Patent of the United States of America is o 1. A device for the purpose specified comprising a casing. a ratchet wheel with a. weight thereon; a pawl actuated by a pendulum for imparting movement to said ratchet wheel to raise the weight thereon;

a disc having a roller and a segmental guide projecting therefrom, keyed on the ratchet wheel spindle; and a disc with radial slots open at their outer ends and curves between said slots turned by the engagement of said roller in a slot as the weight on the ratchet wheel descends.

2. A device for the purpose specified, comprising a casing, a ratchet wheel with a weight thereon; a pawl actuated by a pendulum for imparting movement to said wheel in order to raise the weight thereon; a disc having a roller and a segmental guide projecting therefrom keyed on the ratchet wheel spindle; a disc containing radial slots open at their outer ends adapted to'be engaged by said roller as the weight on the ratchet wheel descends to turn said last mentioned disc, and having curved portion-1 between the radial slots adapted to be engaged by the curved segment for the purpose of locking said disc against turning? movement when the roller is not entered in a radial slot; and gearing between the spindle oi the disc containing the radial holes and a band roller spindle.

3. A device for the purpose specified comprising a casing, a ratchet wheel with" a weight thereon; a pendulum swinging between springbufi'ers; a reciprocatory pawl connected to and actuated by said pendulumi riding on said ratchet wheel; a check pawl engaging the latter; a disc having a roller and a segmental guide projecting therefrom keyed on the ratchet wheel spindle; a second disc containing radial slots open at their'outer cues and curved portions between said slots, keyed on a spindle, so as to be engaged by the roller and guide on the first mentioned disc.

In testimony whereof I have signed my name to this specification in the presence on: two witnesses.
